The study was done to test the biological effects of nonionizing radiation from VDTs and the efficiency of a protective device. Drosophila melanogaster(Cha-C) young embryos were exposed 50 cm in front of a VDT through the whole development period. In a series comprising of 500 eggs in each group the adult mortality among the exposed was significantly increased from 14.7% in controls to 31.9% in the exposed sample, and reduced to 14.3% in the exposed sample under protection of said device (p<0.005). When the exposure started at a later stage of larval or pupal development, no adverse effect was seen on the normal development of the animals. Exposure during varying stages of development showed that the embryonic stage is particularly sensitive, and complementary results had clearly demonstrated the non-reversing noxious action of VDTs. The protective device was found to inhibit the deleterious effect of the exposure as seen in the above-mentioned experiments and restore normal mortality conditions.
